The given equation is
![vw^2 + y=x](https://tex.z-dn.net/?f=vw%5E2%20%2B%20y%3Dx)
And we have to solve for w .
For that we first get rid of y. And for that, we subtract y from both sides,
![vw^2 =x-y](https://tex.z-dn.net/?f=vw%5E2%20%3Dx-y)
Now we need to separate v from w square, and for that, we divide both sides by v, that is
![w^2 = \frac{x-y}{v}](https://tex.z-dn.net/?f=w%5E2%20%3D%20%5Cfrac%7Bx-y%7D%7Bv%7D)
Now to get rid of square, we take square root to both sides. That is
![w= \pm \sqrt{ \frac{x-y}{v}}](https://tex.z-dn.net/?f=w%3D%20%5Cpm%20%5Csqrt%7B%20%5Cfrac%7Bx-y%7D%7Bv%7D%7D)
And that's the required answer.
Answer: 13.2 grams .
Step-by-step explanation:
We are given that ,
In nuclear fusion, about 0.60% of the mass of the fusing substances is converted to energy.
When 22 kilograms of substance undergoes fusion , then the mass of the fusing substances is converted to energy. = 0.06% of (22 kilograms)
Convert % into decimal by dividing it by 100 and replace 'of ' by multiplication operator (x) , we get
Mass of the fusing substances is converted to energy. = ![\dfrac{0.06}{100}\times22=0.0132\ kg](https://tex.z-dn.net/?f=%5Cdfrac%7B0.06%7D%7B100%7D%5Ctimes22%3D0.0132%5C%20kg)
Since 1 kilogram = 1000 grams.
Therefore , Mass of the fusing substances is converted to energy. =![0.0132\times1000 =13.2\ g](https://tex.z-dn.net/?f=0.0132%5Ctimes1000%20%3D13.2%5C%20g)
Hence, 13.2 grams of mass is converted into energy when 22 kilograms of substance undergoes fusion.
Square it -56 + 15k = k^2
re arrange get k^2 - 15k + 56 = 0
factor (k - 7)(k - 8) = 0
solve k - 7 = 0, k - 8 = 0
k = 7 or 8
Answer:
3/6 4/8
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
The expression you need to use would be
3x+12=36.
Subtract 12 from both sides
3x=24
Divide by 3
X=8
